Erm more likelt that you have no partition table yet and so wd0a
doesn't exist... when writing the initial disklabel use /dev/rwd0c
(the RAW partition.)

Unlikely, it's so amazingly simple that there's little to go wrong
(bar user error ;-) ).

Also no. bb_riscbsd has no problems with large disks (AFAIR), as the
only thing written by bb_riscbsd is the bootblock (at the very
beginning of the disk. There are problems with cylinder offset
becoming negative thou'.
NetBSD/arm32 doesn't have the problem that RiscOS does with larger
disks. Although a buglette was found recently and has been fixed that
affected *filesystems* larger than 4GB. There is no (practical) limit
in the size of the disk under NetBSD.
